Valhalla in particular in an in-memory router, so it's holding the whole transportation graph in memory. Not sure about the tiling and geocoding pieces. Most organizations with a "need to serve the world" requirement presumably don't balk at buying all-the-RAMs. Amazingly, the max-RAM-in-machine number has grown faster than the data-in-the-world number, and just being memory bound is a perfectly reasonable design decision, given the performance and complexity wins.
